| 免疫原 | This Histone H4 dimethyl Arg3 (H3R3me2s) antibody was raised against a peptide containing dimethyl Arg3 (symmetric) of human Histone H4. |
| 背景 | Histone H4 is one of the core components of the nucleosome, the basic building block of chromatin. Histones are subject to a variety of chemical modifications, including post-translational modifications of the histone proteins and the methylation of cytosine residues in the DNA. Reported histone modifications include acetylation, methylation, phosphorylation, ubiquitylation, glycosylation, ADP-ribosylation, carbonylation and SUMOylation; these modifications play a major role in regulating gene expression. The methylation of histones can occur on two different residues: arginine or lysine. Symmetric dimethylation of histone H4 at arginine 3 (Arg3), catalyzed by the PRMT methyltransferases, is associated with transcriptional repression. Histone H4 dimethyl Arg3 symmetric methylation (H4R2me2s) is catalyzed by PRMT5 and PRMT7. |

Histone H4 dimethyl Arg3 symmetric pAb tested by Western blot. Western blot performed using Histone H4 dimethyl Arg3 symmetric pAb at a dilution of 1:2,000. Lane 1: Nuclear extract from Raji cells (20 µg). Lane 2: Nuclear extract from HeLa cells (20 µg). | |
Histone H4 dimethyl Arg3 symmetric pAb tested by dot blot analysis. Dot blot analysis was used to confirm the specificity of Histone H4 dimethyl Arg3 symmetric pAb for dimethyl-arginine 3 of histone H4. Peptides corresponding to the immunogen and related peptides were spotted onto PVDF and probed with Histone H4 dimethyl Arg3 symmetric pAb at 1:2,000. The amount of peptide (picomoles) spotted is indicated next to each row. Lane 1: unmodified Arg3. Lane 2: dimethyl-Arg3 H4 (symmetric). Lane 3: dimethyl-Arg3 H4 (asymmetric). Lane 4: monomethyl-Arg3 H4. Lane 5: unmodified Arg26 H3. Lane 6: monomethyl-Arg26 H3. Lane 7: dimethyl-Arg26 H3 (asymmetric). Lane 8: dimethyl-Arg26 H3 (symmetric). Lane 9: dimethyl-Arg2 H3 (asymmetric). Lane 10: dimethyl-Arg2 (symmetric). Lane 11: dimethyl-Arg8 H3 (asymmetric). Lane 12: dimethyl-Arg8 H3 (symmetric). Lane 13: dimethyl-Arg17 (asymmetric). Lane 14: dimethyl-Arg17 H3 (symmetric). |
